ATTACI-EMENT FOR GUNS.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed November 23, 1907. Serial No. 403,545.

T 0 all whom it may concern:

Be it known that I, Gi lzA SZEMEREY, a subject of the Emperor ofAustria-Hungary, and a resident of the city of New York, in the countyof New York and State of New York, have invented certain new and usefulImprovements in Attachments for Guns, of which the following is aspecification.

One of the serious defects of the repeating rifles is that the magazineof the same contains usually either a plurality of ball cartridges, or aplurality of cartridges loaded with shot. It is obvious that themagazine may contain a number of ball cartridges and a plurality ofshot-cartridges, but it will be easily seen that the operator in thiscase will not know whether be fires a ball cartridge or a shotcartridge. On the other hand, when the rifle magazine contains only onekind of cartridges, for instance ball cartridges, and small game comesbefore the hunter, he will hardly have time enough to replace the ballcartridge with a shot cartridge. Vice versa when the rifle is loadedwith shot cartridges and. large game comes before the gun of the hunter,he is compelled to change the cartridges, which may take a considerabletime and after which the game may be out of the reach of his gun.

It is now the object, of the present invention to provide a combinationcartridge, which although being a ball cartridge may be at will andinstantaneously converted into a shot cartridge. i

Another object of the present invention is to provide a mechanism, whichmay be easily applied to a rifle and gun and which is adapted to convertthe ball cartridge, located in the barrel of a gun, into a shotcartridge.

The invention is illustrated in the accompanying drawings, in whichFigure 1 illustrates a longitudinal section of a gun barrel, constructedaccording to the present invention, and containing a cartridge made inaccordance with the invention, Figs. 2 and 3 are perspective views ofthe cartridge converter, shown in difierent positions, Fig. 4 is asectional view of the gun barrel, taken at right angles to the sectionshown in Fig. 1. Figs. 5, 6, 7, and 8 show modifications of the device,and Figs. 9, 10, 11, 12 and 13 show the different stages of manufactureof the combination cartridge.

In order to make the specification more clear, I will first proceed todescribe the combination cartridge, and then the device mounted upon thegun, which converts the ball cartridge into a shot cartridge.

1, in Figs. 913, indicates a strip of suitable material, such as lead,and of a suitable size, which may be rolled so as to form a cylindricalbody 2, open at its ends. One end of the cylindrical body is thencrimped at 3, so as to hold a bottom 1 in place, which latter may bemade of any suitable material, such as a metal of great resistance. Thecylindrical body 2' is then charged with shot 5, and covered by a cover6, similar to the bottom 4., whereupon the free end of the cylindricalbody is crimped at 7. The device, so far described, is then placed intoa cartridge shell 8, which has already been charged with powder 9 andthe usual wad 10. It is obvious that the upper end 11 of the cartridgeshell 8 may be crimped in any suitable manner so as to hold thecombination ball and shot cartridges more firmly. The cartridges soobtained are then used in the usual manner and may, if placed into a gunof the ordinary type, be-used as ordinary ball cartridges.

The converting mechanism is illustrated in Figs. 1 to 4, in which 12indicates the usual barrel of a gun, into which the cartridge,hereinbefore described is placed. 13 indicates the sight on the end ofthe barrel, and at right angles to the sight is indicated the convertingmechanism 14. This mechanism may be mounted upon the barrel near to itsinner end, and comprises brackets 15 15, se

cured to the barrel in any suitable manner. To the brackets is attacheda spring 16 at 17, the free end of which carries a knife 18, fiX- edlysecured to said spring. The inner end 19 of the knife 18 is adapted toprotrude through an opening 20, arranged on the barrel 12. It is obviousthat the opening 20 should be of a size which as nearly as possiblecorresponds to the cross section of the knife 18. Upon the brackets 16is mounted a lever 21 provided with a lug 22 on its inner end, which lugpresses the spring 16 and the knife 18, secured thereto, downward whenthe lever 21 is moved in the direction of the arrow shown in Fig. 1. Themechanism is shown in this position in dotted lines in Fi 1 and in fulllines in Figs. 3 and 4. It wi 1 be observed that the inner end 19 of theknife 88 protrudes in this case through the opening 20 of the gun barreland into the path of the bullet.

A modification of the device is shown in barrel of the gun.

Figs. 5 to 8, in which the knife 18 is forced through the opening 20 ofthe barrel by means of a longitudinally slidable arm 23, which ismounted upon a guide 24, and provided with a finger 25, projecting intothe guide way and normally resting up on the inner end 17 of the spring,as shown in dotted lines in Fig. 5. IV hen now the arm 23 is moved inthe direction of the arrow, shown in Fig. 5, it presses the spring andthe knife, secured thereto, downward, whereby the knife protrudesthrough the opening 20.

The operation of the device is as follows: A combination cartridge isplaced into the Normally the knife 18 is in the position shown in Fig.1, that is it does not project into the path of the bullet. In thiscase, therefore, the cartridge, when fired, will act as a ballcartridge. Should it be desired to use the cartridge as ashot-cartridge,

then the knife 18 is by means of the lever 21 or 23, as the case may be,forced into the path of the bullet, and will, thereby, when the bulletis projected from the gun, cut the shell 2, which, after having left thebarrel, will burst and the shot be freed.

vVhat I claim is:

1. In a gun, the combination with a barrel having an opening near to itsinner end, of a knife located in said opening and adapted to protrudethrough the same.

2. In a gun, the combination with a barrel having an opening, of a knifelocated in said opening and adapted to protrude through the same, andoperating means for said knife.

3. In a gun, the combination with a barrel having an opening, of a knifelocated. in said opening and normally out of the path of the bullet, andmeans adapted to force said knife in the path of the bullet.
